Generating data with sexual offenders using qualitative material: A paradigm to complement not compete with quantitative methodology

This paper proposes triangulation as a research strategy in which the domain of sexual offending may be assessed using both qualitative and quantitative data. Examples of studies that have employed this approach with sexual offenders are outlined, showing the benefit that can be gained from utilizing multiple methods of assessment. The paper also outlines a range of quality criteria when conducting qualitative research, that Gaskell and Bauer (2000) argue are functional equivalents of reliability and validity.
